The iPhone 18 Pro's camera has a variable aperture

The iPhone 18 Pro and Max models introduce a mechanical variable aperture, representing the most significant camera upgrade in years. This new feature enhances the user experience by significantly improving low-light photography capabilities. While some consider it the less exciting of the new iPhone models, the iPhone 18 Pro remains a substantial step up from the previous generation across various aspects, primarily driven by this first-time implementation of a mechanical aperture in an Apple camera system.
